Staking method and staking system

Abstract

A method of placing a slope staking tool including pickets, crossbeams, and a slope beam. The staking method includes: placing the pickets near an intersection C between a current ground and a plane S including a designed slope s; placing the crossbeams on the pickets placed, so as to cross the pickets; searching for a point where a height difference Δh between a predetermined point on the crossbeam and the plane S including the designed slope s, calculated by a surveying device, is zero; and placing, on the crossbeams, the slope beam inclined from the point where the height difference Δh is zero as found in the search step, toward the intersection C between the current ground and the plane including the designed slope.

1 . A staking method of placing a slope staking tool including a picket, a crossbeam, and a slope beam, the staking method comprising:
 a picket placement step of placing the picket near an intersection between a current ground and a plane including a designed slope;   a crossbeam placement step of placing the crossbeam, on the picket placed so as to cross the picket;   a search step of searching for a point where a height difference between a predetermined point on the crossbeam and the plane including the designed slope is zero, the height difference being calculated by a surveying device; and   a slope beam placement step of placing, on the crossbeam, the slope beam inclined from the point where the height difference is zero as found in the search step, toward the intersection between the current ground and the plane including the designed slope.   
     
     
         2 . The staking method of  claim 1 , wherein
 the surveying device is a total station is configured to measure an angle and a distance to a target, and   the search step further includes placing the target at the predetermined point on the crossbeam to calculate a coordinate of the predetermined point.   
     
     
         3 . The staking method of  claim 1 , wherein
 the search step includes notifying by using a notification unit, once the height difference becomes zero.   
     
     
         4 . A staking system comprising:
 a surveying unit configured to measure a coordinate of a predetermined point on a crossbeam of a staking tool;   a coordinate calculation unit configured to calculate a height difference between the coordinate of the predetermined point on the crossbeam and a plane including a designed slope; and   a display unit configured to display the height difference calculated by the coordinate calculation unit.
